Here are the technological facts about renewable energy sources that provide total distinction from the non-renewable kind.

Wind Energy

The wind power is one of the oldest renewable sources of energy. As its speed doubles, its capability can produce an eightfold increase of power generation. There is a greater wind speed on higher places like mountains, hilltops and towers. Ancient civilizations have been using the wind ever since people in ancient countries figured out the use of wind power to pump water. One turbine can produce enough electricity to support up to 290 homes.

Geothermal Energy

The heat produced by the earth’s core can be used as heat pumps which can reduce both energy costs and emissions from saved energy generation. Ground-coupled renewable energy heat pumps are then called ground-source heat pumps, earth-coupled heat pumps, and geothermal heat pumps, though they really do not use geothermal energy in the classical sense.

Solar Power

The invention of solar cooker challenged the consumers of the new millennium. The fact: sun’s heat can even fry an egg in the pavement. In some places of the world, solar cooking is popular usually in large cities where the renewable heat of the sun generates enough energy. When sunlight hits a space with an area of 1 square meter, there is about 1,000 watts of energy from it on that surface which is hot enough to run the solar cooker.

Bio-fuel Energy

Scientists and others discovered that corn plant should be on or near every large farm in every country, which has a bigger number of animals. Their waste could be fertilized to the plant and be transformed into methane gas without having mass land damage. However, the odor involved which would not please the people living nearby. It is calculated that someday, renewable biomass products will supply 90% of the world’s energy in the future.

Hydroelectric Energy

Hydropower is another renewable energy source of the electricity that can generate the fewest greenhouse gases which is 60 times less than power plants that are coal-fired and 19 times less than natural gas power plants. Hydropower plants have an edge over coal fuels in terms of efficiency. Hydropower plants can convert 95 percent of the energy available into electricity while coal plants can only covert 40 percent of the available energy into electricity.

Nuclear Power

Nuclear power plants produced renewable energy that can save thousands of lives every year in every country where nuclear production is abundant. Nuclear plants emit zero carbon dioxide, the greatest pollution contributor in the earth’s vanishing ozone layer.

Understanding through the compiled facts, you must realize why it is being encouraged as the best possible substitution for fossil fuels. It is very important to get a good understanding of these facts to at least be aware that we will never run out of renewable energy in the years to come.

The costs of electricity bills are getting very impractical. The same thing goes especially if you are also feeling the pitfalls of the economic downturn. Since it’s getting harder to tighten one’s belt, it’s always best to look for alternatives. One of the mot popular energy alternatives is solar energy.

Take note that while solar energy is a promising pursuit. You have to understand that there are also downsides. Here are some of the important solar energy pros and cons that you should know.

Advantages of solar energy

Solar energy wouldn’t be as popular if it doesn’t have perks. Below are some that should be in your list.

• No pollution

You can vouch that you wouldn’t be contributing to the overwhelming mess of the world with your solar panels. This is one of the many solar energy pros and cons that you should be aware of.

• Silent

People fear that noise is in the list of solar energy pros and cons. However, this would not be the case. There wouldn’t be any use of renewable energy and fossil fuels. This means that you won’t be using turbines and other noisy tools.

• Space friendly

Note that most solar panels are installed on the rooftop so as not to eat space. There are also remote areas that you can choose to put your panels.

• Efficient

Solar energy is very reliable. Also, almost more than half part of the world is compatible to solar panel installations.

The disadvantages

Part of the reason why people should know solar energy pros and cons is to ensure that they can compromise with the limitations. Here are some of them.

• Relatively big upfront

Prices of solar cells can go as high as $1000. A bigger household might require more solar cells to compensate energy needs. It’s best that you get an estimate from a professional so you’ll know how much it will cost you. The good thing is that the initial costs would be worth it as you can save bigger once the solar panels are running.

• Daylight hours limitation

It is not advisable to choose solar energy as an alternative if you live in a place where there is limited daylight. By the time darkness strikes, your solar cells should have generated enough energy for you to get by during the night.

• Not city-friendly

If you’re living in a polluted city, you can’t probably rely on energy. The thick smog would just be a hindrance to the sunlight. You might not be able to get enough to keep your appliances working. Check to see if the level of pollution in your area can still encourage the use of solar energy.

Think about each solar energy pros and cons so you’ll know what your next move should be. Remember that you can arrive at a deal even if there are advantages and disadvantages. Just make sure that you assess your situation so as not to blur your justification. Decide only when you’ve understand everything.
